Since the discovery of its facile synthesis in 2001, meso-aryl-substituted expanded
porphyrins have been developed as a new class of azaannulenes in light of their facile …

In 1836 the first organoselenium compound, diethyl selenide, was prepared by Löwig, 1 and
it was isolated in the pure form in 1869. 2 Early selenium chemistry involved the synthesis of …

Expanded porphyrins are synthetic analogues of the porphyrins, and differ from these and
other naturally occurring tetrapyrrolic macrocycles by containing a larger central core with a …

This review underscores the conformational flexibility of porphyrinoids, a unique class of
functional molecules, starting from the smallest triphyrins (1.1. 1) via [18] porphyrins (1.1 …

The aromatic character of porphyrins, which has significant chemical and biological
consequences, can be substantially altered by judicious modifications of the parent ring …

The utility of light as a therapeutic agent can be traced back over thousands of years when it
was used in Ancient Egypt, India and China to treat a variety of skin diseases like psoriasis …

Even though the first expanded porphyrin was reported in the mid-1960s, the advances in its
chemistry are more recent. New and powerful synthetic methods have facilitated the …

Porphyrins and expanded porphyrins have attracted the attention of chemists for a long time
in view of their diverse applications in catalysis; as anion, cation, and neutral substrate …

Abstract Expandierte Porphyrine sind synthetische Analoga der Porphyrine und
